How to use

In Vitro:

A77-01 (0.01-10 µM; 25 hours; Mv1Lu cells) treatment effectively inhibits TGF-β-induced transcriptional activation in concentration-dependent fashion. A77-01 (1 µM; 24-72 hours; Mv1Lu cells) treatment efficiently prevents the growth-inhibitory effects of TGF-β. A77-01 (1 µM; 30 minutes; HaCaT cells) treatment inhibits TGF-β-induced phosphorylation of Smad2.
